Mesure des cétones sanguines.

General Description

A portable blood ketone meter used to measure β-hydroxybutyrate (ketone) levels in the blood, often in combination with blood glucose measurement. Useful for individuals with diabetes, those following a ketogenic diet, or in training/high-intensity situations where ketosis needs to be monitored.

 

Main Technical Characteristics

FeatureValue / Details
Parameters measured

• Blood β-ketone (β-hydroxybutyrate)

• Blood glucose (in combined models)

Measurement time

Approximately 10 seconds for a ketone measurement

~5 seconds for blood glucose in combined models.

Required sample volume

Very small: ~1.5 µL for ketone measurement

~0.6 µL for blood glucose.

Sample typeCapillary blood (finger) for ketones; some models also accept capillary or venous blood for glucose.
Accuracy / standardsComplies with ISO 15197:2013 standards for blood glucose in combined models.
DisplayHigh-contrast screen, large numbers/indicators, easy to read even in bright light.
MemoryCapacity to store up to ~1,000 readings depending on model (including glucose and ketones).
Additional functions

• Insulin dose log (diabetic models)

• Blood glucose trend indicators

• No coding required (plug-and-play) for some variants

• Reminders or alerts for high/low glucose based on settings

• Foil-wrapped strips to prevent moisture and contamination.

Size / weightCompact and lightweight; typical dimensions are a few centimeters for the casing, low weight (under 50-60 g depending on model).
PowerButton cell batteries (often CR2032) or similar in portable models.

 

Advantages and Limitations

 

Advantages

  • Allows rapid monitoring of blood ketones, helping to adjust diet, insulin, or training.
  • Requires a small blood volume with a short response time.
  • Combined models simplify glucose + ketone tracking with a single device.
  • Memory & reporting features are useful for tracking trends over time.

Limitations

  • Cost of test strips, especially ketone strips.
  • Requires a finger prick (capillary blood) for any measurement.
  • Accuracy may vary based on hematocrit, temperature, and hydration.
  • Sensitive to correct usage (sample quality, timing of application on the strip, etc.).
